* Revert "Minor cosmetic simplification of case logic after previous patch."...This reverts commit 99a26e5de6d132056999074ce4f4f2cf24ec8c2f. Dale Mellor2022-01-101-25/+25
* Minor cosmetic simplification of case logic after previous patch.... * src/mcron/base.scm: change around some /cond/s and /if/s. Dale Mellor2021-12-301-25/+25
* base: Handle nonexistent user home directories....This is useful for running jobs as the "nobody" user, for example. * src/mcron/base.scm (run-job): Catch the ENOENT (2, "No such file or directory") error when attempting to change directory to the user home directory. Maxim Cournoyer2021-12-301-1/+11
* project: banish need for C compiler...This patch gets rid of the thin veneer that we currently have around the three executables. This was done for historical reasons (circa 2003 Guile couldnʼt deal with process signals and forks). In fact these problems were fixed many moons ago, and there is now no need for it. The project becomes 100% Guile! Many files are affected; interested coders should use the GIT repository to understand the details of all the changes. Dale Mellor2020-04-201-1/+1
* base: Avoid 'call-with-current-continuation'....'call-with-current-continuation' is overkill and not quite what we want. 'let/ec' is supported in Guile 2.0, 2.2, and 3.0. * src/mcron/base.scm (run-job-loop): Use 'let/ec' instead of 'call-with-current-continuation'. Ludovic Courtès2020-02-271-22/+22
* base: Call 'child-cleanup' when 'select' returns an empty set....Previously, on Guile >= 2.2, we'd lose this opportunity to call 'child-cleanup', possibly leaving zombies behind us. * src/mcron/base.scm (run-job-loop): Define 'select*'. Don't expect 'select*' to throw upon EINTR or EAGAIN. Ludovic Courtès2020-02-271-14/+26
* base: Box 'number-children'...* src/mcron/base.scm (number-children): Box it using SRFI-111 to be explicit about the mutability of this object. (update-number-children!): New procedure. (run-job, child-cleanup): Use it. * tests/base.scm ("update-number-children!: 1+") ("number-children: init", "update-number-children!: 1-"): New tests. Mathieu Lirzin2018-03-241-6/+15
* base: Rewrite 'child-cleanup'...* src/mcron/base.scm (child-cleanup): Use recursion instead of 'do'. Mathieu Lirzin2018-03-241-6/+6
* utils: Add 'get-user'...* src/mcron/utils.scm (get-user): New procedure. * src/mcron/job-specifier.scm (job): Use it. * src/mcron/base.scm (remove-user-jobs): Likewise. Mathieu Lirzin2018-03-241-3/+2
* base: Rewrite 'find-next-jobs' docstring....* src/mcron/base.scm (find-next-jobs): Don't explain the detail of implementation in the docstring. Mathieu Lirzin2018-03-241-15/+4
* base: Add '<schedule>' record data type...Reifying the notion of a schedule helps reasoning about the code. Passing a schedule as an argument to related procedures allows writing simpler unit tests. * src/mcron/base.scm(<schedule>): New record data type. (make-schedule, schedule-user, set-schedule-user!) (schedule-system, set-schedule-system!) (schedule-current, set-schedule-current!): New procedures. (system-job-list, user-job-list, configuration-source): Replace those global variables with ... (%global-schedule): ... this global <schedule> instance. * src/mcron/base.scm (use-system-job-list, use-user-job-list) (remove-user-jobs, clear-system-jobs, add-job, find-next-jobs) (display-schedule, run-job-loop): Add '#:SCHEDULE' keyword argument. * doc/mcron.texi (The base module): Update documentation. Mathieu Lirzin2018-03-241-66/+77
* base: Add 'display-schedule' procedure...This procedure is a more generic and less coupled version of 'get-schedule' which has been kept for backward compatibility and deprecated. * src/mcron/base.scm (display-schedule): New procedure. (get-schedule): Move to ... * src/mcron/core.scm: ... here. * src/mcron/scripts/cron.scm (main): Use 'display-schedule'. * src/mcron/scripts/mcron.scm (main): Likewise. * doc/mcron.texi (The base module): Document it. Mathieu Lirzin2018-03-161-27/+19
* base: Add 'run-job' procedure....* src/mcron/base.scm (run-jobs): Delete. (run-job): New procedure. (run-job-loop): Use it. Mathieu Lirzin2017-09-281-31/+20
* base: find-next-jobs: Use functional style....* src/mcron/base.scm (find-next-jobs): Rewrite it using functional style. Add docstring. Mathieu Lirzin2016-12-281-40/+29
* all: Gather module imports....* src/mcron/base.scm: Gather module imports. * src/mcron/redirect.scm: Likewise. * src/mcron/vixie-specification.scm: Likewise. * src/mcron/vixie-time.scm: Likewise. Mathieu Lirzin2016-12-281-16/+12
* maint: Reformat copyright notices and copying permission statements.Mathieu Lirzin2016-12-281-20/+19
* base: Rewrite 'run-job-loop'....* src/mcron/base.scm (run-job-loop): Use #:optional keyword argument, and 'match'. Mathieu Lirzin2016-12-281-44/+33
* base: run-jobs: Ensure that the child process always terminates....* src/mcron/base.scm (run-jobs): Use 'dynamic-wind' instead of 'begin'. Ludovic Courtès2016-05-071-7/+11
* base: Rename (mcron core) module to (mcron base)....The 'configure' script deletes the 'core.*' files. Having a file named 'base.scm' instead of 'core.scm' simplifies the build process without changing the semantics. * src/mcron/mcron-core.scm: Rename to ... * src/mcron/base.scm: ... this. All module users changed. * Makefile.am (MODULES): Add 'src/mcron/base.scm'. (CP): Remove variable. (src/mcron/core.scm): Remove target. (GEN_MODULES): Remove 'src/mcron/core.scm'. (dist_mcronmodule_DATA): Remove 'src/mcron/mcron-core.scm' * doc/mcron.texi: Adapt to name change. * .gitignore: Update. Mathieu Lirzin2016-05-071-0/+270
